Diakinesis is the final stage of prophase I. In human and other mammalian ootidogenesis, the cell (i.e. primary oocyte) is in the arrested state (called dictyate) prior to diakinesis. The rest of the stages of meiosis resumes by the time of puberty. Diakinesis is highlighted by further chromosome condensation, disintegration of the nuclear envelope into vesicles, and the seemingly disappearance of the nucleolus. The four chromatids as well as the chiasmata are now more clearly visible at this point. Meiotic spindle fibers also start to form in preparation for the next stage of meiosis I, the metaphase I.
